In the space
Saturn
Saturn is the sixth planet from the Sun and the second largest planet in our solar system. Adorned with a dazzling system of icy rings, Saturn is unique among the planets. Saturn is a massive ball made mostly of hydrogen and helium. The farthest planet from Earth discovered by the unaided human eye, Saturn has been known since ancient times.

Composition and Structure of Planets | Astronomy
Chemists call such a hydrogen-dominated composition reduced. Throughout the outer solar system, we find abundant water (mostly in the form of ice) and reducing chemistry. The Terrestrial Planets. The terrestrial planets are quite different from the giants. In addition to being much smaller, they are composed primarily of rocks and metals.
What is the Universe?
The universe is nearly 14 billion years old, our solar system is 4.6 billion years old, life on Earth has existed for maybe 3.8 billion years, and humans have been around for only a few hundred thousand years. In other words, the universe has existed roughly 56,000 times longer than our

Our planet Earth is part of a solar system that consists of eight planets orbiting a giant, fiery star we call the sun. For thousands of years, astronomers studying the solar system have noticed
Milky Way
The Milky Way [c] is the galaxy that includes the Solar System, with the name describing the galaxy''s appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye.. The Milky Way is a barred spiral galaxy with a D 25 isophotal diameter estimated at 26.8 ± 1.1 kiloparsecs (87,400 ± 3,600 light-years),

Neptune Facts
Neptune is one of two ice giants in the outer solar system (the other is Uranus). Most (80% or more) of the planet''s mass is made up of a hot dense fluid of "icy" materials – water, methane, and ammonia – above a small, rocky core. Of the giant planets, Neptune is the densest.
What are planets made of?
The planets in our Solar System are spectacularly diverse, from Earth''s ocean-covered surface to mighty Jupiter''s swirling storms and Neptune''s mysterious blue hues. Some planets are more similar than others, and share common structures. When you look at what planets are made of, you get three main groups: terrestrial planets, gas giants, and ice giants.

6 FAQs about [What is our solar system composed of]
What is the Solar System made up of?
Our solar system is made up of the sun and all the amazing objects that travel around it. The universe is filled with billions of star systems. Located inside galaxies, these cosmic arrangements are made up of at least one star and all the objects that travel around it, including planets, dwarf planets, moons, asteroids, comets, and meteoroids.
How many planets are in the Solar System?
Solar system, assemblage consisting of the Sun and those bodies orbiting it: 8 planets with about 210 known planetary satellites; many asteroids, some with their own satellites; comets and other icy bodies; and vast reaches of highly tenuous gas and dust known as the interplanetary medium.
What does the Solar System look like?
On first glance, our solar system seems to be well understood. It includes a single star, planets, their moons, dwarf planets like Pluto and Ceres, and smaller bodies like asteroids, comets, and the outer solar system Kuiper Belt objects.
Which planets are in the inner and outer Solar System?
The inner Solar System includes Mercury, Venus, Earth, Mars, and the bodies in the asteroid belt. The outer Solar System includes Jupiter, Saturn, Uranus, Neptune, and the bodies in the Kuiper belt. [ 35 ]
What is the composition of the Sun?
The Sun is composed of roughly 98% hydrogen and helium, [ 41 ] as are Jupiter and Saturn. [ 42 ][ 43 ] A composition gradient exists in the Solar System, created by heat and light pressure from the early Sun; those objects closer to the Sun, which are more affected by heat and light pressure, are composed of elements with high melting points.
What is a small body in the Solar System?
Any natural solar system object other than the Sun, a planet, a dwarf planet, or a moon is called a small body; these include asteroids, meteoroids, and comets. Most of the more than one million asteroids, or minor planets, orbit between Mars and Jupiter in a nearly flat ring called the asteroid belt.
